How to detect views w/ JDBC?

Thread view: 
Bob Bunch (OCP) - 18 Apr 2005 13:27 GMT
I'm trying to figure out how to tell if a given table (given "select *
from someTableName") using JDBC/Thin is a view.  I've tried using

ResultSetMetaData.isReadOnly(int column) ResultSetMetaData.isWritable(int
column) ResultSetMetaData.isDefinitelyWritable(int column)

...all of which return the same result for a view as a table.  Doesn't
matter if it's a simple or complex view.

I can't employ an Oracle-specific solution for this problem (that'd be WAY
to simple ;) - this needs to be DB agnostic (aka pure JDBC).

Also - this is for a code generator, NOT a to-be-live application.  I'm
generating classes based on a given schema's tables/views, and need to
determine WHAT a given entity is, so I can NOT generate
insert/update/delete methods if the entity is a view.

Any ideas?

Thanks!

Hi,

getTables(...) from DatabaseMetaData seems to do the job :
